To ALL woos: 1mm oononnm Be itlmown that I, A. L. Fiscal,- of the city, county, and State of NewYork, have invented snow and Improved Apparatus for Dissolving Quartz or Silicates in-Water; and I do herebj declare that the following is I a fullnd exact description of the some, reference being had to the accompanyirig drawing, and to the letters of reference being marked thereon.

The nature of my invention consists in a new and improved apparatus for dissolving quartz, silicates, or

silicious ores in water, for the purposeslof extracting therefrom precious metals, and obtaining a liquid hydrate of silica, useful in thearts, as here below more fully described. I

My drawing represents a sectional elevation of my apparatus as viewed through its vertical ce'ntrc.

' Ais a furnacewith a plumbago lining, a a a a, and heated by a fireplace, B, flue C Q'andopeniugs c (we.

D is a drop-trap for discharging the furnace by the tunnel'M. E is a door through which the furnace is charged. F is a cap placed over the furnace, to retard the drought and force the gases through the flues G G.

- is a fireplace for evaporating-the chemicals or producing the gases used in my process.

K is the liquefier or vessel in which th'ooperation of dissolving is finally completed. It consistsjn aniron vessel mounted on a furnace or furnaces, R R, having grates, 02 cf, and of a stirring-apparatus, T, moved by the shaft S and gearings, V.

J is'a bottom valve, worked by a long rod and wheel, N; H is the hlow-otf pipe of'the vessel K;'g is the man-hole; t t a'regauge-coclrs, and r is thegas-pip'ehis the steam-"pipe lcadingfrom esteem-boiler (aot represented in dressings) to the suporheater I. Z'is the steam-electric apparatus invented by me, and fully described in my specification of the some, having its negative polo connected with the shell of the liquefier K, and its positive pole connected with the liquidand materials introduced in said liquefierQ d is the pipe conveying the superheated steamfrom the superheater I to'tlie liquefier' K. ff are settling-tanks, provided, as usual, with plugs or siphoiis for decantation. V is the gas-absorber, with its pipes 13 s, and p, and Y, ,valves q andq', and discharge-plug U. X is the safety valve, and o a stop-cock. M

' The operation is as follows Tlicquart'z or silicates to be treated, previously reduced to the proper degree of divisio' nfare introduced,

either alone or mixed with chemieals,-i.n the furnace A,'where the heat is brought up and kept up to the desired degree by the-action of the furnace B. The mineral in the furnace, having arrived at that-stage of the process requiring 'the introduction of chemicals in n vaporous or gaseous state, the fur nace P is used for vaporizing said chemicals or producing said gases, and the action thereof is either assisted or not by fresh supply of heat from the surface 13.

When the mineral in the Furnace A is suflicien'tly acted upon, and that the process is therein terminated, the trap D is opened, and the auperincuinb at mass drawn out through the tunnel M, to be treated further in the apparatus K." Water is first in'troduc into the vessel K, and steam allowed to blow through the pipe d, when the mineral resulting from the'treatmept in the furnace A- is introduced into the water, and the stirringi apparatus '1 at onceset in motion, and the two electric conductors of the steam-electric apparatus Z connected,

as above mentioned. The man-hole g being closed, and the temperature of the material in,.the liqueficr brought; upto'thc proper degree by the application of heat in the furnaces B. It, and the introduction of steam by the piped kept at the requisite pressure, the solution of the silica in water and disintegration of the oxides takes place.

The gases resulting from the treatment in the liquefier K escape by the pipe 1, and are collected and absorbed in the apparatus V, by water or proper chemicals used for that purpose, in the said vessel V the gases travelling'from thelchambers 1, 2, and 3, by'the pipes S and I, until the gases not absorbed escapeth'rough the pipe Y, while thewnter and chemicals are allowed to drop alternately from the chambers 3, 2, and. .1, by lifting the vuivcsq q, and are finally drawn out by the pi e V.

and the silica dissolved iii the water in the When'th'e quartz o'r silicates are thoroughly disintegrated,

o the settling-tanks ff, where thepreciov" liqnefier, the valve J is opened, and the liquid allowed to flow int metale-are collected by precipitation and decantatiou.

What I claim as my invention, and desire to secure by Letters Patent, is- 1. The above-described apparatus for dissolving quartz or silicates, consisti K, electric apparatus Z, tanksff, and absorber V, arrauged and operating as described.

2: The furnace A, with its fireplace B, furnace I, and trap D, when used for the purposes specified. 3. The Iiquefie'r: K, as above specified. I 4. The combination of the electric mach set forth.
